概要
- 論文の詳細を見る
A transition of a core localized type toroidal Alfvén eigenmode with n = 1 toroidal mode number to two n = 1 global Alfvén eigenmodes was observed in NBI-heated plasmas in the Compact Helical System (CHS) heliotron torsatron. This transition phenomenon is interpreted based on the temporal evolution of the rotational transform near the plasma center caused by the increase in the beam-driven current.
